Abstract (en)

[origin: EP1110493A2] Pressurized filtered exhaust air from a motorized fan in a vacuum cleaner body (2) passes on an exhaust path to a floor suction tool. The exhaust air is directed by the floor suction tool (54) generally parallel to the surface to be cleaned to agitate dust and thus to improve cleaning performance. An electric motor (101) in the floor suction tool drives a rotation brush (60). The exhaust air is also directed toward the rotation brush in the floor suction tool in a direction to add rotation force to the rotation brush. Feeder lines (107) to the electric motor pass through the exhaust path so that the feeder lines are exposed only to filtered air. Passing the feeder lines through the exhaust path avoids the necessity to make special provision for the feeder lines. The exhaust path passes along a hose, and may optionally pass along one or more extension pipes on its way to the floor suction tool. <IMAGE>
